The subdivision of hardware surface processing can be divided into: hardware oxidation processing, hardware painting processing, electroplating, surface polishing processing, hardware corrosion processing, etc.
Surface processing of hardware parts:

1. Oxidation processing: When the hardware factory produces finished hardware (mainly aluminum parts), it uses oxidation processing to harden the surface of the hardware product.

Make it difficult to receive wear.

2. Spray painting processing: the hardware factory uses spray painting processing when producing large hardware products. The spray painting processing prevents the hardware from rust.

For example: daily necessities, electrical enclosures, handicrafts, etc.
3. Electroplating: Electroplating is also the most common processing technology for hardware processing. The surface of the hardware is electroplated through modern technology to ensure product longevity.

There will be no mildew and embroidery under time use. Common electroplating processing includes screws, stamping parts, battery pieces, car parts, small accessories, etc.

4. Surface polishing processing: Surface polishing processing is generally used in daily necessities for a long time. Through the surface burr treatment of hardware products, such as:

We produce a comb. The comb is made of hardware by stamping. Then the corners of the stamped comb are very sharp.

Polish the sharp corners into a smooth face so that it will not cause harm to the human body during use.

The processing method of the surface of the CNC machined part firstly depends on the technical requirements of the machined surface. But it should be noted that these technical requirements are not necessarily parts

The requirements specified in the drawing may sometimes be higher than the requirements on the part drawing due to technological reasons. Such as increase due to non-coincidence of benchmarks

Processing requirements for the surface of some cnc machined parts. Or because it is used as a fine benchmark, higher processing requirements may be put forward.

After clarifying the technical requirements for the surface of each cnc machined part, you can select the final processing method that can guarantee the requirements based on this, and determine the required number

Process steps and processing methods of each process step. The selected CNC machining parts processing method should meet the quality of the parts, good processing economy and

High production efficiency requirements. For this reason, the following factors should be considered when choosing a processing method:

1. The machining accuracy and surface roughness that can be obtained by any cnc machining method has a considerable range, but only in a narrow one

The range is economical, and the processing accuracy in this range is the economic processing accuracy. For this reason, when choosing the processing method, you should choose the corresponding

The processing method that can obtain economical processing precision.

2. To consider the nature of the cnc machined material.
3. To consider the structural shape and size of the CNC machining parts.
4. To consider the requirements of productivity and economy. In mass production, high-efficiency advanced technology should be used. You can even fundamentally change the blank

The manufacturing method can reduce the labor of mechanical processing.

5. It is necessary to consider the existing equipment and technical conditions of the factory or workshop. When choosing processing methods, you should make full use of existing equipment, tap the potential of the enterprise,

Workers’ enthusiasm and creativity. However, consideration should also be given to continuously improving the existing processing methods and equipment, adopting new technologies and improving the technological level.
